Re: Wow, fuck that
8 or 8n or something, i can't remember
i intergrated from 0 to 2pi/n for the acceleration graph, as the area under an acceleration graph is equal to displacement =/
Re: Wow, fuck that
hey for question 3(a) did everyone else get that A=0?
It made no sense to me, like, why would they say x = Acos(nt) + Bsin(nt) if A = 0?
It says it is initially at the origin so at t=0 x=0
which means Acos(0) + Bsin(0) = 0
which turns out A = 0
Wow, fuck that
That was hard man. I usually get 82-81/84 pretty easy in all the past papers i've done, and finished with more than half an hour left
today i was working literally right up until they said pens down. I reckon I'll be lucky to get 80/84. the first part of Q5 took me forever for...
Possibly, apparently everyone found this years exam harder? I don't really think so, i got about 110, which i get in every test.
So yeah, borderline. I think cutoff is usually mid 70s so if the marks were lower across the board you might squeeze in
I ran out of time. I got the 3/2 vt bit and was about to finish the question when they called pens down. So i finished off with a quick 'by inspection, this is equal to whatever'
between 6 and 8 definately. Maybe a couple extra for silly mistakes.
oh well, i'll find out soon with the solutions :D
edit: although, you never know. In the trials there were 2 or 3 marks I was sure i didn't get and I got them. Usually because my Q8 working relies heavily on wording when I...
oh, you're kidding me :D
Even last night, i was like, for intergrals you need to remember the shortcuts for semicircles and the last two on the intergrals sheet
:(
